For jazz’s greatest singers, a humble song becomes a catalyst for proper feats of wonder. Ella Fitzgerald’s prodigious scatting or perfect pitch can be every bit as life-changing as Billie Holiday’s grainy, slow-burn romance. Whether dating back as early as the 1920s (Fats Waller and Bessie Smith) or representing a new century (Michael Bublé and Diana Krall), these singers have fine-tuned the art of phrasing to get the most indelible personality out of each lyric. It’s no surprise, then, that every possible emotion is captured here: feel the forlorn crush of grief and longing, then pivot to the dizzying potential of new love and personal triumphs.
